Siting and Planning for the Ground Run-up Enclosure (GRE) at Billy Bishop Airport


  • Nicholas Sylvestre-Williams Aercoustics Engineering Ltd.


There are requirements that after aircraft maintenance has been completed, engines are required to be tested at take-off power to ensure the proper operation of the aircraft.  These activities can be as short as five (5) minutes but can last much longer, and are generally known as a Ground Run-Up in the aviation industry.  At an engine’s full power, the noise generated can be significant, and for an airport in proximity to neighbouring communities, the noise has the potential to disturb.  To address this concern, Billy Bishop Toronto City Airport (BBTCA) operator, Ports Toronto retained Aercoustics to assist in the siting and impact of a Ground Run-up Enclosure (GRE).  A Ground Run-Up Enclosure is a specially designed enclosure for the aircraft to conduct ground run-ups while minimizing noise to neighbouring to sensitive areas.  This paper will discuss the process in determining the location of the GRE and the modelling of the impacts, with final results of the construction and post-construction measurements.
